Another object of, the invention is the provision of a portable cleaning nozzle which may be; connected to an internal combustion engine of an automobile in such a manner that the running of '10 the engine will supply the power necessary for the operation of the nozzle for cleaning the upholstery of the automobile itself, or other adjacent or nearby objects within the reach of a flexi- 5 tion consists of certain novel features of construc tion, as will be more fully described, and particularly pointed out in the appended claim.

great deal of additionalapparatus, and also one which may be usedin and about objects adjacent the automobile, I have provided a. nozzle which may be operatedby'the pressure developed by the piston of the engine cylinder of the automobile; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferredmeans by which these advantageous results may be accomplished:-

With reference to'the drawing, in designates 10 generally the body of the nozzle which is flared at one end it and extended in the opposite direction to provide a conduit l2 extending therefrom, having a conducting passage l3 which will connect with a suitable collecting bag l4 attached is to one end thereof.

This flared end ll presents an elongated mouth or collecting chamber l5 having a thickened wall portion l6 which is provided with an end surface II in a single plane and an outwardly facing groove II in this surface. A tip designated gene'rally i9 is provided with a face surface 20 to contact or abut the surface It! with an air tight fit. This tip I9 is also provided with a groove 2| which matches up with a groove l1 in the body 4 and which grooves together provide a conduit 22 which extends generally about the elongated mouth opening l5.

One or more jets in bosses 23 communicate with the conduit 22 and are inclined to direct the fluid in the conduit and under pressure upwardly and along the conduit l2 or I3 and cause particles to be drawnv inthrough the mouth [5 that may be adjacent thereto. These jets are shown as 10- cated on'opposite sides of the mouth IE but may also be bored in the bosses 23' at the ends of the mouth, if desired. In order that air pressure be supplied to the conduit 22 I have provided a paswhich passage communicates with the bore 26 in the handle portion 21, the same being controlled byp. valve 28 and pressure being supplied through the coupling 29 from some suitable source of supply.

The control valve v28 islodged within a bore 30 in the handle and comprises a suitable valve seat portion ll to lit the operator's linger and permit air to pass from the bore 20 through the valve seat and the ports I into the conduit iland thence through the lets it and back along the 6 exhaust conduit I3. I The handle 21 is provided with spaced notch portions as at 42 to fit the hand of the operator so that the same may be nicely gripped.

The tip designated generally ll is provided with 10 grooves ll in its face in which a brush ll is located. which in cooperation with the air sucked in through the mouth ll serves to dislodge particles on upholstery or other suriaceswhich are desired to be cleaned and cause them to be 15 dpassedt Iand discharged through the exhaust con- Any suitable pressure may'be coupled to" the bore 20 by coupling II, but a specific use for which this nozzle is intended is a connection to 20 the internal combustion engine 41 of an automobile or motor vehicle, the intemal combustion engine being of the usual type having cylinders and pistons with spark plugs ll for each piston. To attach the device to the engine it is merely as necessary to remove but one of the spark plugs ll and thread into the opening thus left a coupling ll to which the tubular hose ll is connected. As the engine operates, the compression in the cylinder from which the spark plug is removed will 30 be forced through the conduit ll 'and'will enter the bore 2! where it may accumulate as a storage chamber to be supplied to the nozzle under control of the valve tigger lever 8|.

, By this arrangement a unique and simple device is provided which maybe a part of the equipment oi any automobile and which may be easily attached for cleaning the upholstery oi the automobile or by means of a longer hose may be utilizedby some portion adjacent the automobile ior the cleaning of adjacent devices as occasio'n may require or dictate.

The foregoing description is directed solely to'-, wards the construction illustrated, but I desire it 'to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being deconduit, said apertures extending in the direction of the exhaust and aiiording coplanar intersecting jets, and a pressure supply conduit in said body communicating with the groove in said body.
